D6A VAR is Ultra high strength 1930MPa alloy steel, Round bar D6A Shaft Properties Steelmaking, Hot forging, Hot rolling, Heat treatment
TECHNICAL DATA SHEET - D6A
MATERIAL CATEGORY - Ultra high strength 1930MPa alloy steel
MAIN FEATURES: D6A VAC-ARC steel is a medium carbon, low alloy, ultra high strength 1471Mpa steel primarily designed for high strength structural applications.
D6A steel is produced by the consumable electrode vacuum arc remelting process to provide optimum cleanliness and preferred ingot structure, which in turn provide optimum transverse mechanical properties.
OFFICIAL TEST CERTIFICATE - issued by TUV - SGS - BV
